In the recent years, the thermal Hall transport has risen as an important diagnosis of the
physical properties of the elementary excitations in various quantum materials, especially …

The nature of the pseudogap phase of the copper oxides ('cuprates') remains a puzzle.
Although there are indications that this phase breaks various symmetries, there is no …

Phonons are known to generate a thermal Hall effect in certain insulators, including oxides
with rare-earth impurities, quantum paraelectrics, multiferroic materials, and cuprate Mott …

A thermal Hall effect occurs in an increasing number of insulators and is often attributed to
phonons, but the underlying mechanism is not known in most cases. Two main scenarios …

In the context of recent experimental observations of an unexpectedly large thermal Hall
conductivity, κ H, in insulating La 2 CuO 4 (LCO) and SrTiO 3 (STO), we theoretically explore …

Because electrons and ions form a coupled system, it is a priori clear that the dynamics of
the lattice should reflect symmetry breaking within the electronic degrees of freedom …

Motivated by recent experiments on the phonon contribution to the thermal Hall effect in the
cuprates, we present an analysis of chiral phonon transport. We assume the chiral behavior …

It has been known for decades that a magnetic field can deflect phonons as they flow in
response to a thermal gradient, producing a thermal Hall effect. Several recent experiments …

Among the most actively studied issues in the cuprates are the natures of the pseudogap
and strange metal states and their relationship to superconductivity. There is general …

We report theoretical and experimental analyses of the thermal Hall conductivity in
correlated systems. For both fermionic and bosonic excitations with nontrivial topology, we …
